How will you prepare butanoic acid from 1-bromopropane?

Explanation

To prepare butanoic acid from 1-bromopropane, we can follow these steps:

### Step-by-Step Solution:

1. **Formation of Grignard Reagent:**
Start with 1-bromopropane (CH3CH2CH2Br). React it with magnesium (Mg) in an anhydrous ether solvent. This reaction will produce the Grignard reagent:
\[
\text{CH}_3\text{CH}_2\text{CH}_2\text{Br} + \text{Mg} \xrightarrow{\text{ether}} \text{CH}_3\text{CH}_2\text{CH}_2\text{MgBr}
